FEED-ROLL CLUTCH.

Specification of Letters Patent.

Patented Nov. '3, ll ihfi.

Application filed February 17, 1915. Serial Ito. 8,949.

a new and useful Improvement in Feed- Roll Clutches; and I do hereby declare the following to be a full, clear, and exact de scription thereof.

My invention relates to coin handling machines, and is particularly concerned with improvements in the general type of machine illustrated in Patent No. 998,830,

dated July 25, 1911.

Generally stated, this machine is designed for the feeding and stacking of a pre-determined number of coins of a given denomination, the machine being provided with adjustments so that it may be set to operate upon coins of different denominations at different times.

The machine comprises broadly, means for gathering the coins into stacks of a predetermined number, and then feeding each stack to Wrapping mechanism by which a wrapper of the desired number of turns is coiled about the stack and the ends of the wrapper are then crimped in upon the faces of the end coins respectively to form the completed package.

In the operation of the machine, as will be seen from an inspection of the patent aforesaid, the stacking and wrapping mechanisms are operated from a common source. In conjunction with these mechanisms a conveyer is provided to convey the completed stack from the stacking mechanism to the wrapping rolls. When the operation of the machine is started, it is of course necessary first to complete a stack of coins before the wrapping mechanism need be brought into operation. Also it often happens that the Wrapping of one stack of coins will be completed before the stacking of the following stack is completed. Therefore, it frequently happens that while the stack is being formed or completed in the stacking mechanism, there may be no stack of coins present in the wrapping mechanism and the wrapping mechanism has nothing to parts are so arranged and related that both the stacking and wrapping mechanism are continuously in operation, even though as above described, there may be no coins pres ent in the wrapping mechanism to beoperated upon. This results in unnecessary and rapid wear of the wrapping mechanism.

It is therefore the object of this invention .to provide means whereby the Wrapping -mechan1sm may be out of operation at all times, except when a stack of coins has been supplied thereto from the stacking mecha nism, to be wrapped. With this object in view, the wrapping mechanism of said machine has been reorganized so that while the stacking mechanism is operating and there are no coins present in the wrapping mechanism the latter may-be idle, but the moment a stack of coins is, supplied to the wrapping mechanism the latter is tripped into operation to carry on and complete its functions.

In the accompanying drawings which illustrate one embodiment of the invention, Figure 1 is a vertical sectional view taken at the right hand side of the machine, as

illustrated in the patent aforesaid, of so much of said machine as is necessary to illustrate the improvement. Fig. 2 is a rear view of the parts illustrated in Fig. 1; Fig. 3 is an enlarged view of certain parts illustrated in Fig. 1, as seen from the opposite side; and Fig. 4.- is a sectional view on the line 4-4, Fig. 2.

In the embodiment of my invention herein selected for illustration, and referring first to Fig. 2, 2 indicates one of the side standards of the machine frame. Near the top of this frame is journaled a power shaft 3 having splined thereon a clutch member 4 controlled by a clutch operating arm 5 in the usual manner of such construction. The

lower end of the clutch arm 5 is normally actuated by a spring 6 extending to the machine frame 2 in such manner as to cause the engagement of this clutch member with the power member 7 of the clutch, which member is rotatably mounted upon the shaft 3. Said power member is held in adjusted position upon the shaft by the collar 8. The power member of the clutch also is provided with sprocket teeth 9 over which passes a driving chain 10 intended to operate the feed rolls of the wrapping mechanism. This wrapping mechanism is in general of the same construction as that illustrated and described in the patent aforesaid, and comprises in general two wrapping rolls 11 and 12 each rotatably mounted upon shafts 13 and 14 respectively.

The shaft 13 is mounted in a pair of arms 15, and the shaft 1 1 is mounted in a pair of arms 16; the arms 15 and 16 are slotted at 15 and 16 respectively, and are slidably connected together on pins 17 mounted for forward and backward movement on a frame 17 and at their rear ends said arms are pivoted at 152 and 162 on the fixed frame 17 and may be adjusted for the reception of coins of different diameters in the manner set forth in the patent aforesaid. Cooperating with the rolls 11 and 12 is a third roll 18 carried by a pair of arms 18 which in turn swing on a shaft 20 near the base of the machine frame. The feed rolls as they are shown'in Fig. 1 are in open position to receive a stack of coins and may be brought together to bear on the stack by the adjusting mechanism as described in my former patent.

In the construction of the machine heretofore used, the driving connections for the feed roll were constantly operated by the main power shaft of the machine, consequently these rolls frequently were rotating when no wrapping function was to be performed, therefore, they were exposed to heavy and constant wear. In the present construction, therefore, I connect the driving chain 10, Figs. 1 and 2, with the normally idle sprocket 9 on the drive shaft 3. This chain passes about a sprocket wheel 21 on the roll shaft 13, thence around a sprocket 22 on shaft 23 movablv mounted'on the frame l7 and adapted to move in unison with the adjustments of the sprockets of the feed rolls, thence around sprocket wheel 24 on the roll shaft 14, thence around idle pulley 25 on a spindle 26, thence around idle pulley 27 on spindle 28, fixed to the machine frame, thence around sprocket 29 on the shaft 30 of the third feed roll 18, thence around sprocket 31 on the shaft 20 and thence around or back to the loose sprocket 9. In order now that the wrapping rolls may be thrown out of operation at all times except when a wrapping operation is going on, I provide the clutch arm 5 with a pin 32, Figs. 2 and 3, which bears against a cam wheel 33 fixed to the shaft 34?, which also carries the earns 35 which control the crimping operation of the crimper arms andmembers 36, Fig. 1. The

shaft 34.- is directly operated by suitable connections (not shown) with the power shaft 20. The cam 33 is so formed with a cam face 37 that the clutch member 4: will be thrown out of engagement with the loose clutch memher 7 except when the stacking mechanism has delivered a stack of coins to the wrapping mechanism whereupon the cam wheel 33 permits the sliding clutch member 4 to engage the clutch member 7 and bring the wrapping rolls into active operation.

While I have herein described a particular embodiment of my invention it is to be understood that the same may be altered in details and relative arrangement of the parts within the scope of the appended claims.

What I claim is:

1. In a coin handling machine, the combination with coin stacking mechanism of coin wrapping mechanism comprising a plurality of wrapping rolls, means for positively driving said rolls, a clutch connection between said driving mechanism and said wrapping roll and means controlled from the stacking mechanism to trip said clutch into an outer operating position.

In a coin handling machine. the combination with coin counting and stacking mechanism, coin wrapping mechanism ineluding a plurality of wrapping rolls, driving connections for said rolls, a clutch connection between the driving mechanism and said rolls and means controlled by the stacking of the last coin of a stack for tripping said clutch mechanism into operative positions.

3. In a coin handling machine, the combination with a coin stacking mechanism and coin wrapping mechanism including a,

plurality of wrapping rolls, means for driving said roll, a clutch connection between said driving means and said rolls, a cam controlling said clutch connection, said cam being so constructed as to trip the roll driving mechanism into operation when a stack of coins is presented thereto, but to throw said driving mechanism out of operation upon the completion of the wrapping of the stack. 7

In testimony whereof, I, the said JOHN F. MILLIGAN, have hereunto set my hand.
